Today at Mudjin Harbour the sun rises at 6:28 AM and sets at 7:16 PM, with the moon 60% lit. By late evening skies turn fairly clear, so it may be a fine night for stargazing, and low in the western sky after sunset ye may spot bright Venus before it slips below the horizon.

Thursday, August 20, 2026: Across the Caicos banks and cays, the day starts warm near 83 to 84 F with it feeling like 90 to 95 thanks to humidity around 78% to 82%, easterly winds mostly 10 to 15 Miles Per Hour at Mudjin Harbour and Grace Bay and a brisker 14 to 16 at Grand Turk, with waves 2 to 3 feet west and 3 to 4 feet east. Morning turns sunnier in Mudjin and Grace Bay as cloud cover drops under 15%, while Grand Turk stays much cloudier through midday. Even so, rain stays mostly too light to bother most crews, more like passing sprinkles or brief sunshowers. Through the afternoon Mudjin gets hottest, climbing to 87 F with 80% humidity so it feels like 101, while Grace Bay holds steadier near 84 and feeling like 94, and Grand Turk near 84 feeling like 97 with more cloud cover. By dinner time, Mudjin turns overcast, Grace Bay also clouds up, and Grand Turk begins to clear, with east winds around 12 to 15 and waves still manageable for most boaters. The standout difference today is Grand Turk, which stays cloudier and a touch breezier with more 4 foot seas than the other two spots.

Dawn starts near 83 to 84 F, feeling like 92 to 95, with humidity easing through the morning and steady east to southeast winds around 14 to 19 Miles Per Hour. Seas run 3 to 4 feet, with the calmest water around Mudjin and Grace Bay later in the day while Grand Turk stays choppier near 4 feet most of the time. Skies are mostly clear to lightly clouded through morning and midday at all three locations, and rain is nearly absent, making for fine fishing runs, beach time, and smooth outdoor lunch hours. Afternoon temperatures reach about 84 to 86 F, with it feeling like 92 to 98 in the warmer interior of Middle Caicos, while Grace Bay and Grand Turk stay more even near 84. Around dinner time conditions remain friendly with only 5% cloud cover at Grace Bay and Grand Turk and near clear skies at Mudjin, plus steady east winds around 14 to 16. The main difference tomorrow is Mudjin Harbour, which gets a bit hotter inland, while Grand Turk keeps the strongest breeze and the most persistent 4 foot seas.
